Hi Guys!
Well, my quest for a self-supporting tower continues! At last weekend's
W9DXCC I got a lead on a self-supporting 80 foot "Pyrod" tower in use at a
vet clinic. It is holding up some vertical antenna that used to be used
for paging, but isn't anymore.
I looked at the tower, and it seems OK (as much as I can tell). I got some
documentation on the tower (the original schematic drawing from UNR-ROHN -
it turns out that it is about a 13 year old Rohn SSV tower. It appears to
be only the smallest 4 sections (the weakest ones) that you can get. Here
is some info from the drawings that maybe will make sense to someone:
Wind load = 20 P.S.F. w/I (rest of sentence got cut off)
80' SSV TOWER ASSEMBLY
20 P.S.F. E.I.A.
tower height = 80 ft w/ITT
top section: ITT tapered top assembly, 1W, 18ft
next: 2W, 20ft
next: 2WST, 20ft
bottom: 3WN, 20ft
So, what have I got here? Any clue as to how I could find out how much
concrete to put in the ground and how big of an antenna can I put on this
thing (wind load??) I'd like to put a big tribander (TH6/TH7) and a 402-CD
up there. Can it handle that? (I doubt it!) And what does ITT mean?
H--E--L--P!!!
